Purpose


  Move the debugging focus higher up the IDL call stack

Calling Sequence


  DXUP [ , NLEVELS ]

Description



  DXUP moves the debugging "focus" higher up the IDL call stack. By
  using this procedure and DXDOWN, one can navigate up and down an
  existing call stack, and examine and set variables at various
  levels.
  While IDL always keeps the command line at the deepest call level
  (i.e., where the breakpoint occurred), DXUP and its related
  debugging procedures maintain a separate notion of which part of
  the call stack they are examining -- the debugging "focus."
  DXUP moves the debugging focus higher by at least one level, but
  never beyond the "root" $MAIN$ level.

Inputs



  NLEVELS - option number of levels to move. Default (and minimum)
            value is 1.

Example



  dxup
  Move the debugging focus up one level.
